Description
Our precision optical components are crafted from a variety of high-quality materials, each chosen for its unique properties and suitability for specific applications. These materials include Zinc Selenide (ZnSe), Zinc Sulfide (ZnS), Germanium (Ge), Silicon, Calcium Fluoride (CaF2), Sapphire, Fused Silica, SF, and BK7. Each material is meticulously processed to ensure optimal performance, with a diameter tolerance of +0.0''/-.010'' and a thickness tolerance of ±.010''. These specifications are designed to meet the rigorous demands of modern optical systems.
Featuring a wedge surface figure of less than 3 arc minutes and a surface quality of 40/20 or better, these components provide exceptional clarity and minimal distortion. The optical components are designed to achieve a surface figure of λ/40 at 10.6µm for materials like ZnSe and ZnS, while others like CaF2 and Sapphire offer a surface figure of λ/4. Fused Silica, SF, and BK7 can achieve even finer surface figures of λ/10 or λ/20, depending on thickness. This precision ensures that over 85% of the surface meets the specified quality standards, making them ideal for high-performance optical applications.
Our components also feature a controlled chamfer of .01'' - .03'' at 45°, ensuring safe handling and integration into optical systems. The optical coatings available for these components enhance their performance across a wide range of wavelengths, from the ultraviolet (UV) to the infrared (IR) spectrum. Narrowband and broadband coatings are available for both IR and UV/VIS/NIR applications, ensuring low reflectance and high transmittance. Our laserline coatings provide exceptional reflectance, achieving R ≥ 99.5% in the IR range and R ≥ 99.7% in the UV/VIS/NIR range.
These specifications are intended as a general reference and may vary based on specific dimensions and customer requirements. Whether you're seeking spherical lenses, cylindrical lenses, or plano/flat optics, our components are engineered to meet the highest standards of precision and performance, suitable for a wide range of optical applications.
